The Only Aura User In Magic World

"So, does vampires only drink blood?" Albert asked Carrie.

"…no. We can survive just by drinking blood alone, but we can still consume other meal just like other species. Though we prefer meat than vegetables," Carrie said.

"Just like the werewolves, huh? Well, you are now free to join our feast. It's a feast to celebrate our victory against you though. For those who doesn't want to go to our world, you are free to go anywhere. But before you join the feast, I want to ask you where the Vampire Queen is if you don't mind," Albert said.

"Yes. As long as they have no intention in attacking us, everything is fine. And if they want to live in our world, I will need to do some adjustment so your group won't stay in the same place as them," Albert said.

Other than the remains of the Vampire King's army, Carrie and the others here, Albert still wanted to get more vampires? Is he going to build a vampire city in our world?
